作者讨论了诊断成像对患者管理过程的贡献的评估。提出了一个疗效的层次模型，作为评价成像疗效文献的组织结构。在这个层次结构中的每一个较低水平上证明疗效在逻辑上是必要的，但不足以确保在较高水平上的疗效。1级涉及图像的技术质量; 2级涉及与图像解释相关的诊断准确性、灵敏度和特异性。接下来，第3级重点关注信息是否会改变转诊医生的诊断思维。此类变更是4级疗效的逻辑前提，涉及对患者管理计划的影响。5级疗效研究测量（或计算）信息对患者结局的影响。最后，在第6级，分析检查诊断成像技术的社会成本和效益。李博士的开创性贡献B。在影像学诊断研究中的作用也是突出的。
The authors discuss the assessment of the contribution of diagnostic imaging to the patient management process. A hierarchical model of efficacy is presented as an organizing structure for appraisal of the literature on efficacy of imaging. Demonstration of efficacy at each lower level in this hierarchy is logically necessary, but not sufficient, to assure efficacy at higher levels. Level 1 concerns technical quality of the images; Level 2 addresses diagnostic accuracy, sensitivity, and specificity associated with interpretation of the images. Next, Level 3 focuses on whether the information produces change in the referring physician's diagnostic thinking. Such a change is a logical prerequisite for Level 4 efficacy, which concerns effect on the patient management plan. Level 5 efficacy studies measure (or compute) effect of the information on patient outcomes. Finally, at Level 6, analyses examine societal costs and benefits of a diagnostic imaging technology. The pioneering contributions of Dr. Lee B. Lusted in the study of diagnostic imaging efficacy are highlighted.
